# S4 method for class 'Fisher,numeric'
ll(distr, x)

Arguments

df1, df2: numeric. The distribution parameters.
distr: an object of class Fisher.
x: an object of class Fisher. If the function also has a distr argument, x is a numeric vector, a sample of observations.
n: numeric. The sample size.

Value

Each type of function returns a different type of object:

Distribution Functions: When supplied with one argument (distr), the d(), p(), q(), r(), ll() functions return the density, cumulative probability, quantile, random sample generator, and log-likelihood functions, respectively. When supplied with both arguments (distr and x), they evaluate the aforementioned functions directly.
Moments: Returns a numeric, either vector or matrix depending on the moment and the distribution. The moments() function returns a list with all the available methods.
Estimation: Returns a list. The estimator of the unknown parameters. Note that in distribution families like the binomial, multinomial, and negative binomial, the size is not returned, since it is considered known.
Variance: Returns a named matrix. The asymptotic covariance matrix of the estimator.
